How to Clean Roomba Brushes

Before we delve into how to clean your Roomba brushes you need to know where both the main brush and the side brush are located.

The brushes are located in different parts of the Roomba vacuum, so you have to remove them one by one.

How to Clean Roomba Brushes (Main Brush)

There is no rule stating which brush you should start with. However, we will be starting with the main brush, and here is how you should go about cleaning it.

Open up the brush guard

Follow the steps below to open your Roomba brush guard.

  • Place your Roomba on the floor, upside down, on a clean cloth.
  • Next, you will see a pair of long, cylindrical brushes in the centre. They are the main brushes.
  • Additionally, they are covered by a metal gate, so you have to open up the metal guard to access these brushes.
  • Then, pull the two yellow levers on either side of the guard, and they will open up.

Get the brushes ready

When the metal guards are removed, you will find yellow bearings on one end of the brushes.

  • Simply place your fingers on the bearing and lift up the brush.

You also have the grey cap with the square peg. The peg slides into the brush compartment’s groove.

You don’t need to worry about it for now, but you will need it when replacing the brush since you must put the peg into the correct slot.

Take out the hair

Any hair-related filth is usually the most difficult item to deal with.

This is because they tangle the bristles of the brushes and may be densely packed, making it difficult to remove the dirt with your hands.

Because you might struggle with it, here’s how to clean your main brush.

Remove the plastic top

  • If you detect any hair, dirt, or debris within, remove it.
  • Using a microfiber cloth, clean the brush.

NB: You can cut through the knot and remove it with scissors or a razor blade.

Reinstall the brush cylinders

  • After cleaning them all, reinstall the cylinders in the Roomba.
  • That aside, ensure you put the side peg with the grey cap in the appropriate slots on the vacuum.

When you’re done with this part put the brush guard in its rightful place.

How to Clean Roomba Brushes (side brush)

Now, we’ve broken down how you can go about cleaning the main brush. That being said, you need to clean the side brush too.

Nowadays, the majority of Roomba has a tiny, revolving brush on the side. This is done in order to efficiently clean a room’s corners.

In order to remove it, you must unscrew the retention screw at the centre of the brush with a screwdriver. It is found on the side of the Roomba vacuum.

Once the screw is undone, it will be easy to remove and clean the entire side brush.

Clean up the side brush

  • Any dirt, debris, or hair should be removed completely.

Since you won’t be able to remove and clean the brush regularly, make sure nothing is left on it after cleaning.

Reinstall the side brush

Reinstalling it is really simple.

  • Simply reinstall the side brush into the mounting position.

After that, use your screwdriver to push the screw through the middle.
